You should realize it before it's too late.

1. Cry to someone when needed, as it will help you feel better than crying alone.
2. Never compare your life with others. You can not understand what they have gone through.
3. If a relationship needs to be kept secret, you should not be in it.
4. Burn the oil, use expensive lipstick, or wear nice clothes. Do not save them for a special occasion. Every "today" is a special day.
5. Sometimes it's as weird as you like. Do not wait for the old man to wear a purple suit.
6. When you encounter a disaster in your life, ask yourself: "In the next five years these things are still a serious problem or not."
7. What people think of you is not your business.
8. Make the past so that it does not ruin your present.
9. Time will heal everything. So give time time.
10. If you do not ask, you forever have no answer.
